CHARLES E. WAGNER, OF CEDAR RAPIDS, IOWA.

ACETYLENE-GENERATOR.

Specification of Letters Patent.

Patented Aug. 5,1913.

Application filed March 17, 1913. Serial No. 754,785.

To all whom t may concern:

Be it known that I, CHARLES E. VAGNER, a citizen of the United States,and residing at Cedar Rapids, in the county of Linn and State of Iowa,have invented certain new and useful Improvements inAcetylene-Generators, of which the following is a specification.

My invention relates to certain new and useful improvements in acetylenegenerators, and especially to that class where a seal is provided forthe gas-bell when the carbid cartridge has been removed to recharge thesame.

A further object of the invention is to provide a float foraccomplishing this result which will constitute a seal for the gasbellso that the gas remaining in the bell can be utilized after the removalof the carbid cartridge.

A still further object of the invention is to provide a carbid cartridgewhich will slowly feed the carbid to the water, and operating inconnection with the float to be partially controlled in its downwardmovement.

Nth these and other objects in view, the invention will be morespecially described and then claimed, reference being had therein to theaccompanying` drawing, wherein Figure 1 is a central vertical sectionalview of the generator, and, Fig. 2 is a frag'- mentary view of thecarbid cartridge showing means for securing the carbid receptacletherein.

Referring more particularly to the drawing, the reference numeral 10indicates a tank which is preferably sunk into the ground to a depthadjacent the upper end thereof. rfhis tank is provided with a removablecover 11 which permits ready access to the interior thereof, the objectof which will be presently pointed out. The tank 10 has the usual bottomupon which is mounted a vertical guide rod 12. Disposed within said tankis a gas-bell 13, open at its lower end and partially closed at the topas at 14. The bell is of a diameter less than the tank and substantiallyabout onehalf the length thereof so that the same may have a freevertical movement therein. The cover 14 has an opening centrally thereofformed by the frusto-conical member 15 joined at its base to a verticalmember 16, providing a space 17 therebetween for the reception of wateror other sealing fluid.

Removably mounted in the opening provided in the gas-bell cover 14, isthe carbid cartridge 18. The cartridge in its entirety comprises a cover19 to close the central opening in the gas-bell and has an annularflange 2O extending laterally therefrom to rest upon the cover 14 of thegas-bell upon which the same is supported. Any suitable fastening meansas at 21, are provided to secure the carbid cartridge 18 in the gasbell.A handle 22 is provided to facilitate the removal of the cartridge.

Suspended from the cover 19 is a centrally arranged tubular member 23sealed to the cover at its upper end and open at its lower end,perforations 24 being provided adjacent the lower end, the object ofwhich will presently appear. A second tubular member 25 is alsosuspended from the cover 19 and surrounds the member 23, but is of lesslength than said member 23. A U- shaped swinging bail 26 is carried bythe lower end of the member 23 and is disposed below the bottom endthereof. A carbid receptacle 27 closed at its lower end and open at thetop is mounted in the lower end of the member 23 and has fastened uponthe bottom thereof a yoke member 28 to be engaged by thek bail 26 forsecuring the same in position. Perforations 29 are provided in thecarbid receptacle 27, which register the openings 24. Then the carbidcartridge is mounted in the gas-bell, the tubular member 23 extendsdownwardly through the central opening in the gas-bell, while thetubular flange 25 is received within the water seal space 17', toeffectually shut off all communication between the gas-bell 13 and tank10. There is provided a guided float 30 disposed directly beneath thecarbid cartridge and has the top 31 set down into the float body toconstitute a receptacle to contain water. Guides 32 and 33 are providedto direct the float in its up and down movements. The guide 32 engagesthe guide rod 12, while the guide 33 is slidingly mounted on the gasoutlet pipe 34, which also acts as a guide and which extends from thelower end of the tank 10, up into the gas-bell 13. The diameter of thefloat 30 is greater than the lower end of the frusto-conical member 15,and is adapted to receive and seat the same.

The operation of the device is as follows: The usual amount of water isplaced within the tank 10 and the gas-bell 13 descending therein carriesdownwardly therewith the carbid cartridge, the bail 26 upon the lwer endthereof engaging the float 30, to depress the same, and cause the waterin the tank 10 to fill the upper end of the float. The water carried bythe upper end of the float does not come in contact with the carbid, butthe weight of the gas-bell carries the cartridge downwardly into thewater contained within the tank 10, thereby generating gas. The pressureof the gas within the bell 13, will force the same upwardly carryingtherewith the carbid cartridge 18, and the gas escapes through theoutlet pipe 34:. Such operation will permit the iioat 30 to rise andlind its no-rmal floating position and carries upwardly therewith thewater at the upper end thereof. Should the carbid within the cartridgebecome exhausted, the gas will have decreased in volume, therebyallowing the gas-bell to descend in proximity to the float. The bail 26engaging the float 30 will force the same downward a material distance,and it will be readily observed that upon a removal of the carbidcartridge 18, the float 30 will immediately rise, whereupon the upperwater receptacle carried thereby will receive the lower end of thefrusto-conical member 15, and cause a water seal to prevent the escapeof gas from the bell while the cartridge is being recharged and stillpermit use of the tank without an appreciable loss. 1

Having fully described my invention, what l claim as new is 1. A gasgenerator comprising a tank, a gas-bell disposed therein, a carbidcartridge carried by said bell, afloat mounted in said tank, a waterreceptacle upon the upper side of said float to engage said bell andadapted to prevent the escape of gas therefrom upon removal of thecartridge.

2. A gas generator comprising a tank, a gas-bell disposed in said tank,a circular depending member carried by said bell, a carbid cartridgemounted in said depending member, a float disposed below said dependingmember and provided upon the upper side thereof with a water receptaclewhereby the lower end of the depending member is received therein upon aremoval of the cartridge.

3. A gas generator comprising a tank, a

gas-bell disposed therein, a depending cylindrical member carried` bysaid bell, a vertical guide rod and gas-outlet pipe extending upwardlywithin said bell, and-a float guided by said rod and outlet pipe andadapted to come in Contact with said depending member.

4. A gas generator comprising a tank, a gas-bell disposed therein, adepending cylindrical member carried by said bell, a float arranged tooperate directly beneath said depending member, the cover of said iioatbeing spaced below t-he upper marginal edges of said float to provide awater receptacle, the lower end of said depending member to be receivedtherein. f

5. A gas generator comprising a tank, a gas-bell disposed therein, saidbell provided with a central opening in the top thereof and surroundedby a depending cylindrical member, a cover for said opening carrying adepending tubular member to be received within said cylindrical member,a carbid cartridge removably mounted in the lower end thereof, a floatdisposed beneath said carbid cartridge, and said float provided with arecess upon the upper side thereof, the lower end of the cylindricalmember to be received within said recess upon removal of said cover.

6. A gas generator comprising a tank, a gas-bell disposed therein, afloat provided with a depression in the upper side thereof, and meanscarried by said bell and removable therefrom to permit said float toengage the bell.

7. A gas generator comprising a tank, a gas-bell disposed therein, aflo-at provided with a recess for containing Huid disposed within saidtank, means within said tank to provide for a central and verticalmovement of said iioat, and means carried by said bell and removabletherefrom to permit said float to engage the bell.

In testimony whereof I afix my signature in presence of two witnesses.
